Water soluble container

Abstract

A filled water-soluble injection moulded container ( 1 ) containing a first composition ( 6 ) held in a first compartment ( 2 ) and a second composition ( 8 ) held in a second compartment ( 3 ), said first compartment ( 2 ) and said second compartment ( 3 ) being separated by a water-soluble barrier ( 4 ) having an opening ( 5 ) plugged by a plug ( 7 ) arranged such that when said container ( 1 ) is filled with said first composition ( 6 ) and said second composition ( 8 ), said first compartment ( 2 ) is filled through said opening ( 5 ) in said barrier ( 4 ), said barrier ( 4 ) is plugged with said plug ( 7 ), and subsequently said second compartment ( 3 ) is filled with said second composition ( 8 ) and said second compartment is sealed with a closure part ( 9 ).

1. A method for preparing a filled water-soluble injection molded container ( 1 ), said container comprising a first composition ( 6 ) held in a first compartment ( 2 ) and a second composition ( 8 ) held in a second compartment( 3 ), said first compartment and said second compartment being separated by a water-soluble barrier ( 4 ) having an opening ( 5 ) plugged by a plug ( 7 ) arranged such that when said container is filled which method comprises the steps of: providing an unfilled water-soluble injection moulded container ( 1 ) filling said first compartment ( 2 ) with said first composition ( 6 ) through said opening ( 5 ) in said barrier ( 4 ), plugging said opening ( 5 ) with a plug ( 7 ), filling said second compartment ( 3 ) with said second composition ( 8 ) and sealing said second compartment ( 3 ) with a closure part ( 9 ). 
     
     
       2. A method according to  claim 1  wherein said closure part ( 9 ) is a water-soluble film ( 9 ). 
     
     
       3. A method according to  claim 1  wherein said plug ( 7 ) comprises a water-soluble composition. 
     
     
       4. A method according to  claim 1  wherein said plug ( 7 ) is spherical. 
     
     
       5. A method according to  claim 1  wherein said first composition ( 6 ) and said second composition ( 8 ) are each a fabric care, surface care or dishwashing composition. 
     
     
       6. A method according to  claim 5  wherein said first composition ( 6 ) and said second composition ( 8 ) are each a dishwashing, water-softening, laundry, detergent or rinse aid composition. 
     
     
       7. A method according to  claim 1  wherein said first composition ( 6 ) and said second composition ( 8 ) are each a disinfectant, antibacterial or antiseptic composition. 
     
     
       8. A method according to  claim 1  wherein said first composition and said second composition are each an agricultural composition. 
     
     
       9. A method according to  claim 1  wherein said container is made from a poly(vinyl alcohol) (PVOH). 
     
     
       10. A method according to  claim 1  wherein said first compartment ( 2 ) is defined by a lower surface, said barrier ( 4 ) and walls extending therebetween, said lower surface and said barrier ( 4 ) being substantially parallel. 
     
     
       11. A method according to  claim 1  wherein said second compartment ( 3 ) is defined by an opening, said barrier ( 4 ) and walls extending therebetween. 
     
     
       12. A method according to  claim 1  which is cuboid. 
     
     
       13. A method according to  claim 2  wherein said plug ( 7 ) comprises a water-soluble composition.
